ADJUSTABLE HANDLE-CLAMP.

Specification of Letters Patent.

Patented Apr. 23, 1912.

Application filed August 24, 1911. Serial No. 645,777.

To all whom it may concern:

Be it known that I, GEORGE E. "Wnrrrnn, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in AdjustableHandle-Clamps, of which the following is a specification.

This invention relates to improvements in adjustable holders forbrushes, or the like, and an object thereof is to provide a holderincluding an auxiliary handle which may be used as an extension for thehandle of the brush, and which may be conveniently adjusted at differentangles with respect to the brush in the use of the latter.

A further object of the invention is to provide a holder having peculiaradjusting means, and which is neat in appearance and simple andefiicient in construction.

For a full understanding of the present invention, reference is to behad to the following description and to the accompanying drawings, inwhich Figure 1 is a plan view of the invention showing a brush in place.Fig. 2 is a longitudinal section of the device. Fig. 3 is a sectionalview of a modification. Fig. A is a plan view of the retaining washer.

Throughout the following detail description and on the several figuresof the drawings, similar parts are referred to by like referencecharacters.

Referring to the drawings, 1 denotes the handle of a brush which isattached to the holder 2, the latter being carried by the auxiliaryhandle 3.

Describing the construction of the holder specifically, the sameconsists of a disk 4 having a central opening 5 and notches 5 in theedge thereof. The disk has provided on one side thereof spaced lugs 6which have a concave roughened top which forms a bearing for the brushhandle. The auxiliary handle is tapered at one end thereof and formedwith a slot 8, through which slot and the opening 5 of the disk 4: isadapted to pass a clamping bolt 9, the latter being bent to form ahandle engaging hook 10 at one end thereof, and the opposite end beingthreaded to receive thereon a clamping nut 11. A positioning screw 12 isreceived in a threaded opening in the handle and is adapted to beengaged by one of the notches 5 to keep the disk 4 in the desiredadjusted position. It will be noted that the lugs 6 are located to oneside of the disk at sufiiciently to admit of the brush handle beingreceived on said lugs at one side of the clamping bolt, as shown clearlyin the drawings.

In operation, the handle of a brush, or other implement is located onthe lugs 6 provided therefor, under the hook portion 10 of the clampingbolt and the disk turned to give the desired angle to the brush. Thescrew 12 is then engaged with one of the notches 5 and the clamping nut11 tightened to maintain the parts in position. The adjustment of theholder is facilitated by the slot 8 inasmuch as the disk 4 can be movedoutwardly toward the end of the auxiliary handle to disengage the screw12 from the notch in which it is received. The disk may then be rotatedto give the proper angle to the handle and then moved to again engagethe screw 12 in one of the notches 5.

An advantage of the present invention resides in the fact that it is notnecessary to operate the clamping nut for readjustment of the brush dueto the tapered bearing for said nut, a slight pull on the handle beingsutlicient to disengage the screw 12 from the recess 5. Afteradjustment, the handle may again be brought into place and will befirmly caught in position owing to the wedging action against the nut.

In the modified form shown. in Fig. 3 of the drawings, the washer 13 isformed with a lateral extension 14 which is bent to provide anindentation 15 adapted to co'ciperate with a projection 16 on thehandle. By this arrangement it will be seen that the holder will be morefirmly caught in adjusted position and when readjustment is desired, itis only necessary to exert a slight pull on the auxiliary handle,thereby disengaging the indentation 15 from the projection 16simultaneously with the screw 12 becoming disengaged from the notchedportion of the disk at. After desired adjustment of the brush, the partsmay then be brought back to their locked position and retained thereinby the above described cooperation of the elements 15 and 16. It will beseen that, in this manner, a very rigid connection of the parts may beobtained.

Having thus described the invention, what is claimed as new is:

1. An adjustable brush holder comprising a disk having an openingtherein and notches in the edge thereof, lugs carried on a side of thedisk, a handle having an elongated opening therethrough, a positioningscrew carried by the handle and adapted to cooperate with said notches,and a clamping bolt passing through said opening in the disk and theopening in said handle, the clamping bolt having a handle engagingportion and adapted to thereby clamp a handle in position, the latterbeing caught between the aforesaid lugs and the handle engaging portionof the clamping bolt.

2. An adjustable brush holder comprising an auxiliary handle having aslot there-- through and being tapered adjacent to said slot, a diskhaving a notch in one side thereof and an opening therethrough, a handleengaging lug carried by the disk, a clamping bolt passing through theopening in the disk and through the slot in said h andle and furtherhaving a clamping nut adapted to cooperate with the tapered portion onsaid handle, thereby frictionally retaining the holder in adjustedposition, and means carried by said auxiliary handle co acting with thenotch in said disk, thereby preventing rotation of the disk.

3. An adjustable brush holder comprising an auxiliary handle having aslot therethrough and a projection adjacent to said slot, a disk havingan opening therethrough, a handle engaging lug carried by the disk, aclamping bolt having a handle engaging portion and passing through theopening in the disk and through the slot in the auxiliary handle, awasher carried by the clamping bolt and having a lateral extensionformed with an indentation, said indentation being adapted to cooperatewit-h the projection on said handle to prevent longitudinal movement ofthe handle, and means for preventing rotative movement of said disk.

4. An adjustable brush holder comprising an auxiliary handle having aslot therethrough and a projection slot, a disk having an openingtherethrough, a handle engaging lug carried by the disk, a clamping bolthaving a handle engaging t portion and passing through the opening in ithe disk and through the slot in the auxt iliary handle, and a washercarried by the clamping bolt and having a lateral extension formed withan indentation, said indentation being adapted to cooperate with theprojection on said handle to prevent j longitudinal movement of thehandle.

In testimony whereof I atlix my signature in presence of two witnesses.
